The President of the United States of America, authorized by Act of Congress, July 2, 1926, takes pleasure in presenting a Fourth Bronze Oak Leaf Cluster in lieu of a Fifth Award of the Distinguished Flying Cross to Major Floyd E. Heinzig (AFSN: FR-64830), United States Air Force, for extraordinary achievement while participating in aerial flight as an F-105 Thunderchief Pilot over North Vietnam on 17 September 1967. On that date, Major Heinzig led a force of twenty F-105 aircraft against a railroad yard and bridge in North Vietnam. Despite the intense anti-aircraft fire, surface-to-air missiles, and numerous hostile aircraft sightings, Major Heinzig pressed his attack and dealt major damage to the hostile installations. The outstanding heroism and selfless devotion to duty displayed by Major Heinzig reflect great credit upon himself and the United States Air Force.
